The energy self-sufficient sludge2energy system for sewage sludge utilisation is based on the combination of a sludge dryer and subsequent incineration in a fluidised bed furnace.

The innovative process contributes to sustainable waste management and thermally utilizes sewage sludge by incineration. Co-generated heat is used for sludge dryer operation. The sludge2energy system is a sustainable and lasting solution that provides security of thermal sewage sludge utilisation according to the current political requirements.

Through energy self-sufficient sludge drying and incineration, the sludge disposal volume is minimized to approximately 10%. The ash remaining from the incineration process permits later recovery of the resource phosphorus.
